Abstract
In this paper, the equations which evaluate the fabric quality for underwear knitted fabrics are derived bycorrelating the subjective quality assessed by experts with the fabric characteristic values which have beenselected in the Part 1 in this series.
On the basis of analyses of the correlation between the subjective quality and each of the characteristicvalues, some of the thermal/water transport properties are omitted. The properties used for the equations are : the primary hand values and the thermal/water transport properties such as qmax (a measure of warm/coolfeeling), Qw (heat loss to air through fabric placed on a wet paper which simulates wet human skin), K' (heatconductance).
The equations are derived by using a multivariable regression method on the basis of subjective qualitydata and fabric characteristic values for the 73 samples which have been sampled from comercial fabrics so asto cover the wide range of quality and type of underwear.
It is confirmed that the derived equations predict the fabric quality well within the same error as thatobserved between individuals of the experts. The quality assessment by consumers are also carried out tocompare the quality by experts and consumers. A good correlation between them are obtained. This resultproves the generality of the equation derived by the experts' judgement.
The contribution of each of the characteristic values to the fabric quality is analysed for each case of expertsand consumers and the result shows also a close similarity between these two groups.
